The boring comment here: Almost anything can or cannot be romantic... It depends on the parties. I have a wife and two kids... In the rare occasion I can walk with my wife, only the two of us, that can be romantic even when walking in general is not romantic
Argentinian here... Most of the immigration here, like 85%, is Spanish and Italian (pre and post wars). My family came here before 1920, from different parts of Spain, like it happened in the US and many countries across the continent. That said, it's true many nazis came here to hide after the war, some more hidden than others but most were not in Buenos Aires because they could be easily exposed. This happened also in Chile, Paraguay and Brazil. Why this happened? Probably contacts with the governments and even today South America has almost zero immigration control, nazi or not. Another less known fact is that Argentina has one of the biggest Jewish communities. You can Google it 😊
